server problem -- help needed.
I am trying to figure out a weird server load problem, I've been using the commands top, vmstat, "watch -n1 pstree" and iostat to try and find the source of the problem. After a couple of weeks of watching the output of these commands, and reading everything I can find on system load problems, I am still not a lot closer to working out what's going on.
Some server load graphs, and command results.
http://64.21.181.70/tmp/load.php
The load problem often happens during off peak hours, eg.. 5pm GMT, 6am GMT.
I've only had this server for a couple of weeks, my old server was pretty much the same spec as this machine, and the high loads never happened before the move. I've disabled as many non essential services as possible (analog, webalizer etc..) to see what effect it has on the load problem, but its still happening.

I've noticed errors (between 250 - 350 per day) just like the one below in the error_log file.
[Sun Mar 3 23:56:12 2002] [notice] child pid 21976 exit signal Segmentation fault (11)
These errors seem to happen most hours of the day and not just during the weird high load periods.
I also noticed the following thread http://www.webhostingtalk.com/showth...threadid=33463
talking about the "Intel Corp. 82557 [Ethernet Pro 100]" card and the eepro100 driver, I have looked in the /etc/modules.conf file and my system is using this driver.
So what do you think?
Could the segmentation faults be the cause?
Is the driver the problem?
Is it something else?
Help
